Agree with the person who rated Claude Young. Saw him and Colin Dale on same bill at Orbit and the music was top.
Also at Orbit, Sven Vath (96 time) managed to play a set with loads of subliminal rythms and the place just WENT OFF.
Went and saw him a few years later and had to leave cos the last tune he played was such a pile of toss. How times change.
Immersion live (I believe, though was a little worse for wear) at Glastonbury Traveller Field (1999?) was also memorable.
